Downpour
11 February 2021 11:02:58


Significant warm up beginning to surface on the GEFS. With the blocking patterns around it still looks like an early taste of spring or last bit of winter are both more likely than a standard Atlantic flow.

Ready to see snowdrops popping up – could be a very rapid transition to proper spring looking at the charts.


Roll on spring :)

Looks good and still on the dry side too.
Things are so late here so far, with snowdrops barely showing yet.
On the plus side the rabbit population has collapsed

I’m with Justin. I’m looking for adjustments to warmer uppers - done chasing winter now. If we (IMBY) are not going to get a snow day out of what was looking like a decent set-up then it’s warm sunshine I’m after.

The interesting this here is that the 2018 and 2021 easterlies were both preceded by marginal events from the west that brought a lot more snow. We had ~8cm on Jan 24th 2021 and ~15cm on December 10th (or thereabouts) 2017.

Writing definitely on the wall now for this is slightly underwhelming cold spell. BBC 5 dayer (I know these things are about as accurate as a chocolate fireguard) has 6c for Saturday and 10c with disgusting amounts of rain and cloud for Sunday.


Winter is over. Roll on Spring.

still plenty of colder options on the GEFS. The upstream pattern still not yet resolved, though odds now strongly favour mild

We may see an update from them in the next day or two reflecting the milder output (If it's still there in a day or two). 


The High could easily drift to a more favourable position for cold later. \i think even if we get these warmer temps they're not likely to last, still too early in the season for persistent warmth and colder again later is equally if not more likely.

In their defence they already said it would turn milder with only the northeast holding onto temperatures near to average. It's in the second part weeks 3&4 they are expecting the return of the cold as the high pressure system drifts westward.

When its this cold I cannot get in the drivers side of my Landie as the door freezes solid and I need to climb over the passenger side.  Very inelegant!


Worth it for the snow but the Chilts have been snowless in this episode!

This winter has been consistently cold without delivering real cold.I think this is going to go on until April despite the forcast at present. Expecting Scotland and NE England to be hard hit again before spring summer weather arrives.Whether this winter is the start of a new cluster who knows .

Disappointing (for those who like snow) to see the zeros creeping back into the snow row figures on Brian's GFS ensemble graphs.  I wonder when we'll see our first run with all zeros?

At least the "echo easterly", which we're still in, was cold enough for it to be snow this time!


Incidentally one of the odd things of this spell has been GFS - which has consistently underestimated temperatures. (It has -4C for now, for example, for here, whereas it's actually just -0.3C. It had a high of -2C, when it was +0.3C - and so on. I don't really know why it's doing it, but it's been persistent for several days now.)
